NONSLIP DEVICE FOB, HORSES.

Application filed November 23, 1924. Serial` No. 752,768.

T0. all whom t may concern.'

Be it known that I, MICHAEL llinniNnN, a citizen of the United States, residing at New York city, in the county of New Yorlr and State. of New Yorlr., have invented certain new. and useful Improvements in a Nonslip Device for Horses, of which the following is a speciiicatio-n.

My invention relates to non-slip devices for horses, of the type which can be readily attached to and detached from the horse-s foot by the driver, and is particularly intended for use in connection ywith the inventions disclosed in my Patents No. 1,207,030,

r dated December 1916, and No. 1,473,425,

dated November 6, 1923, it being my object to provide simplified means for solidly loching the device to a horses shoe so that it will not loosen in use and to so protect the locking means that said means will not be liable to accidental damage whereby its removal or attachment is rendered difficult. Another object is the more rigid attachment of the body of the device to the horseshoe before a detachable callr plate is secured to the body.

In the drawing Fig. 1 is a view of my iin proved device secured to a shoe, disclosing the side next to the hoof; Fig. 2, a detail view of the inside of a removable calli plate and locking device; Fig. 3, a view of the device on a horseshoe showing the side next to the ground; Fig. 4, a. sectional view ofthe structure of Fig. 1 on the line 4 4 thereof; Fig. 5, a sectional view of the structure of Fig. 1 on the line 55 thereof; and 6, a view of the structure of Fig. 1 on the line 66 thereof.

The device comprises two opposed clamp plates 1 and 2 connected by a turnscrew 3 entering a tapped hole in hubs 4 and 5 on each plate, with the threads in opposite directions, so that by turning the screw the plates can be forced apart or drawn together. To protect the screw-threads against accidental damage the half-round protectors 6 and 7 extend from the tapped hubs and are interposed between the screw and the ground.

The plate 2 consists of a thinned plate or flange 8 adapted to pass between the metal shoe s and the hootl and an outer bearing surface 9 provided with calls 10, 11 and 12 adapted to bear on the ground, the shoe entering the groove between the parts 8 and 9j rlhe hub 5 has a boss 13 extended at right angles thereto and is tapped to receive a lock screw 14, the head of which enters a countersink in its outer end and its point entering a longitudinal groovevor slot 15 in the screw 3 to prevent the same from turning after the device hasbeen expanded inside a horseshoe. i i

In the drawing l have shown the opposed plate 1 of the type used where it is'desired to malte use of a detachable calli plate which can be replaced when worn.- lt comprises the thinned flange 16 adapted to pass between the shoe and hoof, the threaded hub 4, and the ove-rhanging projection 17, Vwhich is a counterpart to the recess 18 in the call( plate 19 shown in Fig. This projection 17 lies on the outside of the shoe which is between it and the flange 16. 1t is. therefore possible to solidly lock the device to a horseshoe before the detachable calk plate 19 is secured in place, whereas in my prior patents the calli plates were usedas part of the securing means and which, if loosened in use, allowedthe wholenon-slipping device to become loose on the horses foot and most probably lost.

The calk plate 19 has a groove 2O on its inner face adapted to receive the hub of the plate 1 andthe end 18 receives the projection 17. The calli plate is secured to the plate 1 by means of screws 21 and 22', the heads of which are countersunk as shown in Fig. 5 whereby the screws are protectedV from accidental damage. This calli plate 19 has the calks 21, 22 and 23 on its bearing Vface and is generally placed so as to come on tor 6 which enters a slot 15 in the turnscre'w Y' plates together, the device is slid into the shoe on the horses hoof and then expanded until solidly locked thereto after which the lock screw 14 is entered into one of the slots in the turn screw.

If the lock screw 14 is omitted, as it may be if the calk plate form of construction isemployed, the calk plate is removed, the clamp plates expanded inside the horeshoe with theprojection 17 on the lower face of the shoe, after which the calk plate is secured to the main plate, the key 24C entering a slot in the turnscrew to prevent rotation.

v By the use of either or both of these locking' devices the rotationof the turnscrew is prevented and the device cannot become loose in use and lost.

Vhile I have shown both Jforms of locking device to pr-eveii't rotation of the turnscrew, in practice but one of these forms is used in the production of my device, preferably thescrew form.

By this construction the device will it either the front or the hind feet of a horse and on either the nigh or oii side, making its attachment quick and easy, as no select-ion is required as in the case of special devices for each foot.

I claim l. A non-slip device for horses, comprising a pair of 'opposed plates, a hub on each of said plates, said hubs being tapped inopposite directions, a turnscrew` entering said hubs and provided with a longitudinal slot,

and a locking device carried by one of said plates adapted to enter the screw slot to prevent rotation thereof'.

2. .A non-slip device for horses, comprising a pair of opposed plates, a hub on each of said plates, said hubs being tapped in opposite directions, a turnscrew entering' said hubs and provided with a longitudinal slot, a tapped boss on one of said hubs, and a screw entering said boss and adapted to extend into they slot on the turnscrew to prevent rotation of the latter.

3. A non-slip device for horses, comprising a pair of opposed plates, a hub on each of said plates, said hubs being tapped in opposite directions, a turnscrew, enteringsaid hubs-and provided with a longitudinal slot, a countersunk tapped boss on one of said. hubs, and a screw entering said boss and adapted to extend into the slot Von the turnscrew to prevent rotation of the latter `and wilt-h its head adapted to lie within the oountersink. l f

Ll. A non-slip device for horses, comprising apair of opposed plates, a hub on each side of said plates, said hubs being tapped in opposite directions, a turn-screw entering said hubs, inwardly extending protectors projecting from said hubs and adapted to lie between the turnscrew and the ground, and a locking` device carried by one of said hubs and adapted to engage the turnscrew to prevent rotation thereof.

In testimony whereof I have aiiXed my signature.

MICHAEL HALLANAN.
